User Defined Error Responses

To return an error response as the output of an endpoint cell with a particular HTTP status code, the notebook cell should return a dictionary with a status key and HTTP status code as its value, as well as an error object containing a name with the desired exception name and a message key with the desired error message.

CODE

response = { 'status': 400, 'error': {'name': 'MyException','message': 'Could not compute'}}
response

Alternatively, the endpoint code can raise an exception and Data Lab Functions will compose the error response. However, the HTTP status would be 500.
